Abstract
An improved material gathering device is for a mining machine or the like of the type which includes a mobile body supporting a mining head at a forward end thereof for dislodging material from a mine face. A gathering platform is on the mobile body adjacent and below the mining head for receipt of the dislodged material thereon. An endless conveyor extends longitudinally of the mobile body to convey the dislodged material away from the forward end to the rearward end of the mobile body. A pair of oscillating arms are on transversely opposite sides of the gathering platform and are driven by a gear train including a transversely extending shaft to cause the arms to feed the dislodged material onto the endless conveyor. The endless conveyor includes a sprocket and drive shaft at a forward end thereof to cause the endless conveyor to extend into the gathering platform to terminate near a forward edge thereof. The drive shaft for the endless conveyor is coupled by gears to the transversely extending shaft of the pair of oscillating arms.
